KUDU-3662: Add stress test for checkpoint recovery
Add TestReplicationCheckpointStress to verify data durability under
extreme failure conditions. The test aggressively triggers the
checkpoint race condition by:
- Creating table with multiple partitions (high split count)
- Inserting data continuously across partitions
- Repeatedly crashing and restoring from checkpoints mid-replication
- Verifying no data loss after multiple crash/recovery cycles
Test validates that the checkpoint race condition fix in
MetricWrappedKuduEnumerator correctly handles:
- Splits finishing between snapshot and checkpoint completion
- Multiple concurrent splits in various states (active, buffered)
- At-least-once semantics with idempotent UPSERT sink operations
Test stability: Timeouts carefully tuned based on checkpoint and
discovery intervals to avoid flakiness. Verified by running 1024
iterations on dist-test with debug build - no flakiness detected.
